Can You Have Both an HSA and FSA at the Same Time?

You can have both an HSA and FSA, but the rules depend on which type of FSA you have

If you have a Dependent Care FSA, you can hold an HSA at the same time with no restrictions. If you have a Healthcare FSA, the answer is more complicated. You cannot contribute to both in the same year — but you can have an HSA and a Limited-Purpose FSA (also called a Limited FSA) together, and you can switch between them in certain situations.

The reason for this restriction comes from how the IRS defines HSA may be able to access. To contribute to an HSA, you must be enrolled in a High Deductible Health Plan (HDHP). A regular Healthcare FSA is not compatible with an HDHP because the FSA covers costs before you meet your deductible, which violates HSA rules. A Limited-Purpose FSA, by contrast, only covers dental and vision expenses, so it does not interfere with the HDHP structure.

Key Takeaways

You can hold a Dependent Care FSA and an HSA at the same time without any conflict.
You cannot contribute to a Healthcare FSA and an HSA in the same year, even if you have both accounts.
A Limited-Purpose FSA and an HSA can coexist because the Limited FSA only covers dental and vision care.
If you switch from a Healthcare FSA to an HSA, you must stop contributing to the FSA and let any remaining balance roll over or be forfeited depending on your plan rules.

How a Healthcare FSA blocks HSA contributions

The IRS rule is strict: if you are covered by a Healthcare FSA at any point during a calendar year, you cannot contribute to an HSA that same year. This applies even if the FSA and HSA are through different employers or if you stop contributing to the FSA partway through the year.

The reason is that a Healthcare FSA lets you pay for medical expenses with pre-tax dollars before you have met your deductible. An HDHP requires you to pay out-of-pocket up to a certain amount (the deductible) before insurance kicks in. If an FSA is paying those costs, you are not actually meeting the deductible requirement, and the HSA loses its tax advantage. The IRS considers this a violation of HSA rules.

If you are currently contributing to a Healthcare FSA and want to switch to an HSA, you will need to drop the FSA coverage. Some employers allow you to make this change during open enrollment or if you have a may have access to life event (marriage, birth, loss of coverage). Check with your benefits administrator about when you can make the switch.

Limited-Purpose FSAs work alongside HSAs

A Limited-Purpose FSA (sometimes called a Limited FSA or post-deductible FSA) is designed specifically to work with HSAs. It covers only dental, vision, and sometimes hearing expenses — not general medical care. Because it does not pay for medical services that would otherwise count toward your deductible, the IRS allows you to hold both at once.

This combination is popular with people who want the long-term savings of an HSA but also want to set aside pre-tax money for predictable dental and vision costs. You contribute to both accounts in the same year, and each has its own annual contribution limit. For 2024, HSA limits are $4,150 for individual coverage and $8,300 for family coverage; Limited FSA limits vary by employer but are typically $2,500 to $3,050.

If your employer offers a Limited-Purpose FSA alongside an HDHP, this is usually the clearest path to having both accounts. Ask your benefits team whether your plan offers this option, or whether your Healthcare FSA has a "limited" or "post-deductible" version.

Dependent Care FSAs have no HSA conflict

A Dependent Care FSA covers childcare, adult day care, and similar expenses for dependents while you work. It has nothing to do with medical coverage, so the IRS places no restriction on holding one alongside an HSA. You can contribute to both in the same year without any problem.

Dependent Care FSAs have their own annual limit, which for 2024 is $5,000 per household per year (or $2,500 if you are married and file taxes separately). This limit is separate from your HSA and Healthcare FSA limits, so you can max out all three if your employer offers them.

What happens if you have both accounts and change jobs

If you move to a new employer and that employer offers different coverage options, you may find yourself in a position to switch. For example, your old employer might have offered a Healthcare FSA, but your new employer offers an HDHP with a Limited-Purpose FSA. In this case, you can stop contributing to the old Healthcare FSA and start contributing to the HSA and Limited FSA at your new job.

Any money left in your old Healthcare FSA will be subject to your former employer's plan rules. Most FSAs operate on a "use it or lose it" basis, meaning you forfeit any unused balance at the end of the year. Some plans offer a grace period (usually 2.5 months into the next year) to spend remaining funds. Check your old plan documents or call the FSA administrator before you leave to understand what happens to your balance.

If you had an HSA at your old job, that account stays yours. HSAs are portable — you own them, not your employer — so you can keep contributing to the same HSA at your new job if you remain enrolled in an HDHP.

Switching from Healthcare FSA to HSA mid-year

Some life events allow you to change your health coverage outside of open enrollment. If you lose Healthcare FSA coverage due to a may have access to event (such as losing your job, your spouse's job, or your dependent status), you may be able to enroll in an HDHP and start contributing to an HSA immediately.

The key is timing: you can only contribute to an HSA for months during which you are not covered by a Healthcare FSA. If you drop your Healthcare FSA in June, you could theoretically contribute to an HSA for July through December, but the IRS prorates your annual contribution limit based on the number of months you are may be able to access. This calculation is complex, and mistakes can result in tax penalties, so work with your employer's benefits team or a tax professional if you are making this change.

Frequently Asked Questions

If I have a Healthcare FSA, can I open an HSA and just not contribute to it?

No. The IRS rule is about coverage, not contributions. If you are enrolled in a Healthcare FSA during any month of the year, you are ineligible to contribute to an HSA that year, even if you do not put any money into the HSA account. You must drop the Healthcare FSA coverage first.

Can I use my HSA to reimburse myself for FSA expenses?

No. Money in an HSA and money in an FSA are separate. You cannot transfer funds between them or use one account to reimburse expenses paid from the other. Each account has its own rules about what expenses it covers and how you can spend the money.

What if my employer offers both a Healthcare FSA and an HDHP?

If your employer offers both, you must choose one or the other for that year. You cannot enroll in both the Healthcare FSA and the HDHP at the same employer. However, if the employer offers a Limited-Purpose FSA instead of a Healthcare FSA, you can enroll in both the HDHP and the Limited FSA.

Do I lose my HSA if I switch to a Healthcare FSA?

You do not lose the HSA account itself, but you cannot contribute to it while you are covered by a Healthcare FSA. Any money already in the HSA stays there and can be used for medical expenses at any time. Once you drop the Healthcare FSA coverage, you can resume HSA contributions.

Can I have an HSA and a Dependent Care FSA from different employers?

Yes. Dependent Care FSAs do not conflict with HSAs, so you can hold both even if they come from different employers. Just track the contribution limits for each account separately to avoid exceeding the annual maximum.
